The Kinetics of Extended Chain Crystallization in Polymer Processing @ Oklahoma State University
9301693 Tree Flow-induced crystallization of semi-crystalline polymers to produce extended chain crystals provides an opportunity to produce lightweight, high-strength materials from inexpensive feed stocks by carefully controlling the processing variables. The project will bring together researchers from the fields of polymer processing, thermodynamics and computer simulation to study flow- induced crystallization kinetics. The research will use a specially designed rheometer and a newly developed rheo-optic technique to obtain in-situ, quantitative measurements of flow- induced crystallization kinetics in crystallizable polymers. Anew model of polymer crystallization kinetics, based on current molecular theory for polymer molecules, will be developed and incorporated into a simulation of polymer processing in order to optimize the design of polymer processing operations with respect to the degree of extended chain crystallinity, which in turn is directly related to the mechanical properties of the product. The research may allow the production of high performance plastic parts from inexpensive polymer materials through the careful control of processing variables.

Development of a High Speed Web Line (Ari/Mme) @ Oklahoma State University
9413814 Good State-of-the-art equipment to support research in the Web Handling Research Center (WHRC) will be developed. The WHRC is a National Science Foundation Industry/University Cooperative Research Center in its ninth year of operation with twenty corporate sponsors. The term "web" describes materials that are manufactured and processed in a continuous-strip form, e.g., thin plastics, paper, textiles, metals, and composites. Web handling refers to the physical mechanics related to the transport and control of continuous-strip materials through processes and machines. The equipment to be acquired will support several research projects, including: (1) winding webs at high speed and accelerations, (2) longitudinal dynamics and tension control in multi-span web transport systems, and (3) the wrinkling of webs. The sucessful research performed with the web line should have an impact upon productivity within web handling industries. The amount of web handling which is done within industry is immense as many automated manufacturing processes demand the continuous strip form. The investigator's will be able to validate and improve some of the most critical mathematical models that have been developed. The result will be an improved knowledge base which engineers can use to design web process lines that produce the required product without defects and losses resulting in improved productivity.

I/Ucrc Competitive Renewal: Operating Center Proposal For An Industry/University Cooperative Research Center: I/Ucrc For Measurement and Control Engineering @ Oklahoma State University
ABSTRACT EEC-9978598 HIGH
This proposal is for renewal of an I/UCRC on measurement and control engineering which was originally established at the University of Tennessee. The present proposal outlines multi-university collaboration between the University of Tennessee and Oklahoma State University. The existing center will be expanded by partnering with OSU which adds advanced process control with a focus on modeling and experimental computer intensive studies. The program includes one investigator from Eastern Carolina University.
The current research program emphasizes two areas: analytical Instrumentation and process control optimization and modeling. UTK faculty are involved in both research areas, whereas, OSU faculty are involved only in the process control optimization and modeling area. The proposal does not clearly delineate changes in the research focus of the previously funded center that is to be accomplished by adding the OSU program. Industrial involvement and membership are of high level and considered strength.

Collaborative Proposal: Operating Center Proposal For Continuing An Industry/University Cooperative Research Center: I/Ucrc For Measurement and Control Engineering @ Oklahoma State University
The Measurement and Control Engineering Center is an interdisciplinary research and educational Center directed toward the development of new sensors and control systems. These technologies are critical to the modernization and continued competitiveness of US manufacturing industries, including chemicals, petrochemicals, and pharmaceuticals, inter alia. This action provides continued funding for a multi-site Center with the lead site at the University of Tennessee and an affiliate program in a critical needs industrial area (advanced control, including modeling and simulation) at the Oklahoma State University.
